Embedded Web Server Based on Freescale Platform
Šilon, Peter ; Vašíček, Zdeněk (referee) ; Strnadel, Josef (advisor)
Embedded web server (EWS) is a web server that runs on a device with limited computing power and memory. By implementing a web server into embedded device with network connectivity we achieve new way of long distance management and control. Web technologies offer user-friendly GUI, simplicity and low prices. The aim of this project is a design of the EWS using Freescale resources. EWS have to have a slot for memory card, on-board peripheries or interfaces signals attached to connecter to allow connection of external devices. Firmware will be built on one of the freeware TCP/IP implementation for embedded systems.

Asymmetric Multiprocessing on the ARM Cortex-A9
Riša, Michal ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
Asymmetric multiprocessing (AMP) is a way of distributing computer system load toheterogeneous hardware and software environment. This thesis describes the principles of the AMP focusing on the ARM Cortex--A9 processor and Altera Cyclone V hardware platform. Development of a OpenAMP framework based AMP system showing communication among the processor cores, documentation and future work suggestion are the products of this thesis.

Implementation of RTOS into STM32 microcontrollers with ARM Cortex-M4F core
Gothard, Adolf ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This masters's thesis deals with choice and implementation of two free real-time operating systems into powerful 32-bit microcontroller with ARM Cortex-M4F core. First, there is shortly described the ARM architecture in general, its programmer's model, instruction set and Cortex-M4F core in brief. Next is description of the architecture of used microcontroller STM32F407VGT6 from ST Microelectronics, description of its integrated memories and their organization and functions of its integrated A/D and D/A converters. Next part of this thesis deals with searching real-time operating systems with ARM Cortex-M4F core support and then choose two of these systems for the implementation. The chosen operating systems are more closely described in two following chapters. Next chapter analyses possible implementations of the digital PSD controller and more complex system of such controllers using real-time operating system. Following chapter describes implementation of chosen operating systems and designed controllers. Last chapter deals with evaluation of features and qualities of the chosen real-time operating systems for implementation of embedded control system.

Small CNC machine
Moštěk, Jiří ; Matěj, Zdeněk (referee) ; Záplata, Filip (advisor)
This diploma thesis deals with the design and construction of a three-axis CNC machine primarily designed for PCB drilling and production of front panels for various electronic devices. All three axes are driven by stepper motors NEMA 23 which are connected to stepper motor drivers L6470. Processor STM32F407 is used to control the whole machine. The wiring is completed by a LCD display with touchscreen which is used to communicate with user. Data for drilling can be entering manually or via USB inerface. Part of this thesis is the selection of a suitable construction and components, assembling equipment, wiring design of electronic circuits and writing the code to control the machine. Finally, the parameters of the designed device have been measured.

Firmware for the Robotic Vehicle
Otava, Lukáš ; Sojka,, Michal (referee) ; Kučera, Pavel (advisor)
This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

Implementation of the I2S Driver into the Freescale MQX RTOS
Možný, Karel ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
This thesis deals with design and development of a I2S module driver for real-time operating system MQX running on a ColdFire V4 architecture based processor. Further there are presented circuit diagrams and PCBs created for testing of functions and properties of the driver. Signal input is a digital audio in form of S/PDIF interface, output is an analogue signal, that can be listened by the means of a headphone amplifier. The conclusion describes a sample application demonstrating function of the driver on developed hardware.

Measuring temperature inside PC
Rataj, Tomáš ; Kolka, Zdeněk (referee) ; Michálek, Václav (advisor)
This master’s thesis deals with measuring temperature inside personal computer. The main goal of this work is to develop tool which is able to measure temperatures in several places, display a store the values. Theoretical section is concentrated on selection of temperature sensor, that have suitable interface for microcontrollers and has sufficient accuracy for this application. In next part there is complete hardware and software design of instrument. Software solution is based on real-time operating system. Device is projected as a battery-operated compact tool. With created application for personal computer, measured data can be downloaded through USB and displayed in graphic format.

Present-day Programming Method of Microcontroller
Medla, Eduard ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to modern methods of programming microcontrollers. In this work are examined some programming languages, various programming environments and graphic editors. In every methods of programming are explained their advantages and disadvantages. Here are two examined methods of loading program to microcontroller, so called flashing. Choosed method is programming language C, which was used to programme two-state regulator with hysteresis in environment AVR Studio 6.2.
